PRAIRIE DU SAC, Wis. (SPECTRUM NEWS) - The weekend cold snap will not affect an already compromised grape crop in Wisconsin. However, for grape-growers, this is the worst season they can remember.

"It was a cold winter and it was an early frost in the spring, so that lessened our crop," says Julie Coquard, owner of Wollersheim Winery. "We had to purchase more grapes to supplement the lack of grapes that we had from our vineyards this year and frankly, that's not just us, but all over Wisconsin."

Randy Hartung owns Three Branches Vineyard in Arena, Wisconsin. He is also the president of the Wisconsin Grape Growers Association.

"The tiers of the southern counties experienced the majority of the frost damage, the northern counties experienced more of the winter damage," says Hartung. "The east from what I've been told experienced minimal damage, but they had a lot of rain and erosion."

Hartung says the southern counties only harvested about 30% of their crop this year due to a frigid winter, an early frost, and too much rain. 

Both Hartung and Coquard say they're thankful for what they did harvest.

"Quality from what I'm hearing from all growers I've talked to say what they harvested was good to great, actually were some of the terms," says Hartung.

"In the end, we had a good quality crop, just a lot smaller than usual," says Coquard.

Hartung also adds this weekend's early cold weather is good for the grapevines, after harvest. It signals to them it's time to sleep for the winter.
